Sample request

Basic format The app admin sends ordinary group messages, and the sender is the app admin.
{
"GroupId": "@TGS#2C5SZEAEF",
"Random": 8912345, // A random number. If the random numbers of two messages are the same within five minutes, they are considered to be the same message.
"MsgBody": [ // Message body, which consists of an element array. For details, see the field description.
{
"MsgType": "TIMTextElem", // Text

"Text": "red packet"
}
},
{
"MsgType": "TIMFaceElem", // Emoji
"MsgContent": {
"Index": 6,
"Data": "abc\u0000\u0001"
}
}
],
"CloudCustomData": "your cloud custom data",
"SupportMessageExtension": 0,
"OfflinePushInfo": {
"PushFlag": 0, // Normal push
"Desc": "Content to push offline",
"Ext": "Passthrough content",
"AndroidInfo": {
"Sound": "android.mp3"
},
"ApnsInfo": {
"Sound": "apns.mp3",

"Title":"apns title", // APNs title
"SubTitle":"apns subtitle", // APNs subtitle
"Image":"www.image.com" // Image URL
}
}
}
Specifying the message sender The app admin can specify a group member as the message sender in From_Account. After receiving the message, other members will see that the message is sent from the group member specified by the app admin.
{
"GroupId": "@TGS#2C5SZEAEF",
"From_Account": "leckie", // Message sender (optional)
"Random": 8912345, // A random number. If the random numbers of two messages are the same within five minutes, they are considered to be the same message.
"MsgBody": [ // Message body, which consists of an element array. For details, see the field description.
{
"MsgType": "TIMTextElem", // Text
"MsgContent": {
"Text": "red packet"
}
},
{
"MsgType": "TIMFaceElem", // Emoji
"MsgContent": {
"Index": 6,
"Data": "abc\u0000\u0001"
}
}
]
}
Specifying the message recipient If To_Account is added to the message body, and a message recipient is specified in it, the message will be sent only to the specified recipient, and the message is excluded from the unread count. (Supported group types: Private, Public, ChatRoom)
Note
This feature is supported only in the Premium edition.
{
"GroupId":"@TGS#12DEVUDHQ",
"Random":2784275388,
"MsgBody":[
{
"MsgType":"TIMCustomElem",
"MsgContent":{
"Data":"1cddddddddq1"
}
}
],
"To_Account":["brennanli2", "brennanli3"] // Specify the message recipient (up to 50 recipients can be specified). If this field is used, the message is excluded from the unread count.
}
Specifying that messages do not trigger conversation update If SendMsgControl is set to NoLastMsg, it indicates not to trigger conversation update; if it is set to NoUnread, it indicates not to include the message in the unread count (this field cannot be used for audio-video groups (AVChatRoom). For meeting groups (Meeting), messages are excluded from the unread count by default, and you need to enable the feature; otherwise, an error will be reported when NoUnread is set).
{
"GroupId": "@TGS#2C5SZEAEF",
"Random": 8912345, // A random number. If the random numbers of two messages are the same within five minutes, they are considered to be the same message.
"SendMsgControl":["NoLastMsg"],// Do not trigger conversation update.
"MsgBody": [ // Message body, which consists of an element array. For details, see the field description.
{
"MsgType": "TIMTextElem", // Text
"MsgContent": {
"Text": "red packet"
}
},
{
"MsgType": "TIMFaceElem", // Emoji
"MsgContent": {
"Index": 6,
"Data": "abc\u0000\u0001"
}
}
]
}
Specifying the message priority You can specify the message priority. The default priority is Normal. There are three priority options in descending order: High, Normal, and Low. They are case-sensitive.
{
"GroupId": "@TGS#2C5SZEAEF",
"Random": 8912345, // A random number. If the random numbers of two messages are the same within five minutes, they are considered to be the same message.
"MsgPriority": "High", // Message priority
"MsgBody": [ // Message body, which consists of an element array. For details, see the field description.
{
"MsgType": "TIMTextElem", // Text
"MsgContent": {
"Text": "red packet"
}
},
{
"MsgType": "TIMFaceElem", // Emoji
"MsgContent": {
"Index": 6,
"Data": "abc\u0000\u0001"
}
}
]
}
Forbidding callback for a message When the callback switch is turned on, users can specify ForbidCallbackControl to control whether to initiate callback for a single message. By default, callback is initiated.
{
"GroupId": "@TGS#2C5SZEAEF",
"Random": 8912345, // A random number. If the random numbers of two messages are the same within five minutes, they are considered to be the same message.
"ForbidCallbackControl":[
"ForbidBeforeSendMsgCallback",
"ForbidAfterSendMsgCallback"], // Callback forbidding control option
"MsgBody": [ // Message body, which consists of an element array. For details, see the field description.
{
"MsgType": "TIMTextElem", // Text
"MsgContent": {
"Text": "red packet"
}
},
{
"MsgType": "TIMFaceElem", // Emoji
"MsgContent": {
"Index": 6,
"Data": "abc\u0000\u0001"
}
}
]
}
Sending group @ messages The mentioned users (@) set in the GroupAtInfo field have a one-to-one and sequential correspondence to the mentioned @ users in the message body.
Caution
Audio-video groups (AVChatroom) don't support the @all feature.
{
"GroupId": "@TGS#2C5SZEAEF",
"Random": 8912345, // A random number. If the random numbers of two messages are the same within five minutes, they are considered to be the same message.
"MsgBody": [ // Message body, which consists of an element array. For details, see the field description.
{
"MsgType": "TIMTextElem", // Text
"MsgContent": {
"Text": "red @all @tommy @brennanli packet"
}
}
],
// It corresponds to @all @tommy @brennanli in the text information.
"GroupAtInfo":[
{
"GroupAtAllFlag":1 // `1`: @ all ; `0`: @ a certain group member
},
{
"GroupAtAllFlag":0,
"GroupAt_Account":"tommy" // @ a specific group member
},
{
"GroupAtAllFlag":0,
"GroupAt_Account":"brennanli"
}
]
}
Specifying messages for online delivery without offline or roaming retention If OnlineOnlyFlag in the message body is set to a value greater than 0, the message is for online delivery only, not for offline or roaming retention (not available for AVChatRoom or BChatRoom).
{
"GroupId": "@TGS#2C5SZEAEF",
"Random": 8912345, // A random number. If the random numbers of two messages are the same within five minutes, they are considered to be the same message.
"OnlineOnlyFlag": 1, // The message is for online delivery only (only online group members will receive it), not for offline or roaming retention.
"MsgBody": [ // Message body, which consists of an element array. For details, see the field description.
{
"MsgType": "TIMTextElem", // Text
"MsgContent": {
"Text": "red packet"
}
},
{
"MsgType": "TIMFaceElem", // Emoji
"MsgContent": {
"Index": 6,
"Data": "abc\u0000\u0001"
